Protein Extraction & Lysis Cell / Tissue Lysis

Cell or tissue lysis, fractionation and sample preparation are crucial tools for the purification, analysis and identification of proteins and their functions or roles. Unfortunately, there is no single procedure or protocol for optimal protein sample preparation as the techniques used are dependent on numerous factors, including starting sample and downstream analysis techniques.

Astral Scientific offers a wide selection of protein extraction and lysis buffer systems. The range includes products that maintain biological activity of proteins (PE LB™ systems), strong chaotropic extraction buffers that are 2D compatible (2D-Xtract™, FOCUS™ Extraction Buffers) and extraction systems for total proteomes (FOCUS™ Proteome kits).

Common lysis buffers (RIPA), extraction tools (grinding resins), enzymes (lysozyme and Zymolyase® inhibitors and other extraction accessories are also offered.

Our Protein Extraction & Lysis Buffer (PE LB™) systems ensure good protein recovery, while maintaining the biological activity of the proteins. The solubilized proteins are suitable for enzyme assays, electrophoresis, folding studies, chromatographic studies and many other downstream applications.


The PE LB™ systems are based on a proprietary combination of organic buffering agents, mild non-ionic detergents, and a combination of various salts to enhance extraction of proteins and maintain stability of biological activities of the proteins.
